To aZZ 'wlw/m t may concern.'

.Be it known that I, RAOUL Lonr, a subject of the French Republic, residing at St. Benoit-sur-Loire,Loiret, France, have in. rented new and useful Gearing, of which the Following a specification.

The object of my: invention is to replace the hand driven mechanism by mechanical means.

The apparatus' consists of a 'trame work supporting the mechanism, described in my application Serial No. 54(1527/1910 lzfigure 1 is a vertical section ot' the apparatus, Fig. 2, is a side view of the apparatus.

The apparatus is composed of a cross piece a., toothed pinions c which are engaged with the liXed wheel c asfwell as with the threaded tubes g. Tliesliat (Z carries a brakepulley 2` instead' ota crank and a toothed pinion 3, ixed on the shaft. This pinion gets an intermitting movement by means` ot a too-thed sector which is fixed loosely on thel nave 5 of the pulley G which latter is also lixed loosely on the shaft. T. A loose pulley is placed at one side of the pulley (3 and `runsalso `loose upon the shaft. The movement ot the sector 4 is effected by means vo1 an elastic abutment t), composed of a tube l() tixcd on the pulley G, in which is placed a springl 11, being),` in contact with a piston l2 which is `lixed on the sector 4. Close to the sector 4 is situated a cam 13 for the purpose ot raising' the lever lliof the brake 2, in order to retard rotation of the wheel 2, this brake maybe regulated by means of a nut 15. The lever isbrought back continuously by the spring` 16 which is fixed partly on the frame-work and on its exterior' end on the lever 14.

The working ot' the'apparatus is as fol-` lows: The belt drives the pulley t3, and by means of the elastic abutment 9, and also the toothed sector 4, the pinion is driven.

vThe pinion 3 is turned one or more times according;` to the number of the teeth of the `sector until the cam 13 raises the roller of the lever 14, this effects the braking of the pulley by means of its brake-band; an-

easy action, because the pinion 3 is at this time .no more in touch with the teeth of the sector' 4. The time of stopping the apparatus is necessary in order to place the locks of hair between the two wires, and while the rotation of the pulley 6 continues, the cam ldeaves the 'lever 14, and the latter becomes engaged by the spring. The sector engages itself at once with the first tooth ot' the pinion and by means of the elastic .abutment a sudden shock is avoided which would break the teeth 1n a short'time; the I.f startnre` of the apparatus 1s consequently 'ley and sector, a cam driven by said pulley,

and brakemechanism actuated by said camy and coacting with said brake wheel to arrest rotation ot the shaft when said sector is out o1 gear with said pinion.

2. An apparatus of the class described comprisilne` in combination, a driven shaft and a brake member therefor, means for intermittently driving said shaft., adriviner pulley and a yielding connection between said pulley and said means, and brake mechanism actuated by said pulley and coacting; with said brake member to arrest rotation ot said shait when `the latter is not driven by said means, substantially as de.- seribed.

In testimony whereof l aliix my signature in presence of two Witnesses.
